If you have an iPhone, you're going to make a note of this.
It was discovered on Monday that a bug in Apple's FaceTime video chat software (on devices with iOS 12 or newer) allows users to hear the person they're calling – without the person picking up.
The flaw was first reported by 9to5Mac, which discovered the bug and describes that it can be accessed by dialing another Apple user, then inserting your own number through the "Add Person" feature while the call is ringing.
FaceTime then assumes it's dealing with a group conference call and opens up audio on the receiver's side, letting you listen in to them without them being aware.
And it gets worse, too, as The Verge reports that if the recipients hits the "power" or "volume" button to ignore the call, it not only broadcasts audio, but activates the video as well.
Apple is working on a fix for the bug, Gizmodo reports, which it said should be ready later this week.
In the meantime, users are advised to disable FaceTime. If you have an iOS device like an iPhone, go to "Settings" and switch the toggle on the FaceTime icon to gray.
On a Mac, open the FaceTime app, click FaceTime in the menu bar and select "Turn off FaceTime."
